If you carry out ROT and RUT work and are not registered in the population register in Sweden and therefore cannot get a Swedish eID, you can apply here for payment for ROT and RUT work. This is the case irrespective of whether you have carried out the work in Sweden or in another EEA country. Under "Download brochures" you will find the form you need to apply for payment. Note that there are different forms depending on whether the payment is for ROT or RUT work.
If you have a Swedish eID, you have to use the e-service.
